`LYlI/IAN ARNOLD COOK, OF WOONSOGKET, RHODEISLAND.

, IMPROVEMENT IN MACHINES FOR FEEDING RIVETS ANDINSERTING THEM IN SHOES,&c.

Specification forming part of Letters Patent No. 112,554, dated March14, 1871.

To all persons to 'whom these presents maycome:

Be it known that I, LEMAN ARNOLD COOK, of Woonsockeuof the county ofProvidence, of the State of Rhode Island, have made a new and usefulinvention` having reference to the feeding of rivetsto and insertingthem in a shoe or other article.; and I dohereby declare the same to befully described in the following specification `and represented in theFigure 1 is a front elevation, Fig. 2 a verl tical and longitudinalsection, and Fig. 3 an end elevation,of such invention or mechanism.

In such drawing, A denotes a magazine or I hopper, arranged so as toslide freely on a tube, B', and over an opening, a, in such tube.

h i The part b of the hopper also serves as avalve to close the saidopening.

The tube B extends from a hollow cylinder or box, C, arranged to slidefreely on and to I boot or shoe may be turned around on the tube in amanner to carry any part of the sole to be nailed or riveteddirectlyover the upper termi# nus Vof the tube.

A driving-shaft, F, disposed over the tube,

`and supported in suitable boxes, asl shown at e f,ha`s cranked wheels g71l `at'its opposite ends. One of these wheels is connected to thepiston of the air-pump by a rod, t', and serves to Work such piston. Theother crank-Wheel operates avert-ical slider, 7c, carrying an awl, l,for piercing the sole or other material to be riveted. There is alsoanother shaft, m, over the tube E, such shaft having a feed-Wheel, on,

and a ratchet-wheel, n, fixed upon it.

The ratchet is to be revolved by a pawl, o, Worked by an eccentric, p,fixed on the driving-shaft, the saine being to revolve the feedwheelwith an intermittent motion.

A forked lever, Gr, pivoted in thel frame, spans the hopper slide-box C,and is connected thereto by pins or studs projecting from the box andinto slots made in the prongs of the lever.

A rod, H, leads from the upper arm of the said lever to the clasp I ofan eccentric, K,

`iixed on the driving-shaft, all being as represented.

If We suppose the magazine or hopper to be charged with rivets, and ashoe to be arranged on the tubular horn or upper part of the tube orconduit B, with the upper end of such tube against the inner surface ofthe sole, and the tube to beforced upward so as to carry the uppersurface. of the sole against the feedwheel, and the driving-shaft be putin revolution, the following results will take placethat is to say, theshoe-solewill be fed along with an intermittent motion, will bepunctured by the aWl, and, as the aWl-hole may be brought over the upperterminus of the tube B, a rivet will be blown from the magazine throughthe tube and into such hole, the said rivet being subsequently upset orclinched by other means. As the hopper may be moved back and forth outhe tube B, the hopper A will alternately open and close the passage a,in order that, when it may be open, a rivet may descend into and throughit from the hopper or magazine, and When the hole is closed the pistonof the air-pump may descend in the pump-barrel and compress the airtherein.

It should be mentioned that While the hole a may be open, or during apart of the time it .may be so, the pistou will be ascending and drawingair through the hole into the cylinder or pump-barrel. I

I claim- 1. The combination of the tube or conduit B, the magazine A,the air force-pump c, the feeder m, and the awl l, all being arrangedand applied together, substantially in manner and to operate asexplained. y y

2. The tube B, as applied to the air-pump conduit and the frame, inmanner so as to be capable of being moved to carry the work to beriveted either up to or away from the feeder, as occasion may require,all being substantially as explained.
